Mikroe Motion 3 Click is based on the EKMC1606112 PIR motion sensor from Panasonic. This click also features the TLP241A photorelay from Toshiba. This provides reinforced galvanic isolation for the external signals used to drive some external high power electronic equipment when motion is detected. It allows up to 40V between the SSR contacts in OFF state, and currents up to 2A while in ON state, thanks to a very low ON-state resistance.
